He did not carry away more than ten at each plunge, for he was obliged to pull them from the bank to which they adhered by means of their strong byssus
. And how many of those oysters for which he risked his life had no pearl in them!
attachment weakened by ocean acidification.
As we examined a clump of blue mussel Mytilus galloprovincialis planulatus stranded at the high tide mark by recent heavy seas, I observed the rear end and leg of a crustacean in the dark murky recess of a dead bivalve, Barbatia pistachio, attached to the mussels by a byssus
Pour l'instant, "on n'a trouve aucune parade", indique le biologiste marin francais Nardo Vicente, de l'institut d'oceanographie Paul-Ricard, specialiste de ce coquillage dont la fine barbe, le byssus
, aurait servi, selon la legende, a tisser la celebre Toison d'or de l'Antiquite grecque.
This pair of ganglia have twice the size of the cerebral and visceral ganglia, and are located at the base of the pedal organ (foot) attached to the first pair of anterior retractor muscles of the byssus
. From each ganglion emerges the pedal nerves, which penetrate to the posterior pedal retractor muscles and enter the foot.
Correlations between shell metrics [shell height (SH); hinge length (HL)] and byssus
size [byssus length (BL) and byssus
diameter (BD)] to mobility are also recorded and analyzed.
Mollusks response to contamination, relative to their mobility, to avoid an adverse condition (escape and attraction) such as some mussels when released from their byssus
(anchor structure), in the presence of irritants or marine gastropods are attracted to areas with a high content of organic matter.
The expensive cloth was woven from rare 'sea silk' fiber that had been taken from the whiskers of a mollusk called 'byssus
.' The veil is transparent, with the beautiful image of the face of Jesus remaining clearly visible whether viewed from the front or the back.
The proceedings, comprising 17 papers, discuss such topics as byssus
and sea silk: a linguistic problem with consequences, dyeing wool and sea silk with purple pigment from Hexaplex trunculus, sacred colors, purple textiles in Greek sanctuaries in the second half of the first millennium BC, purple wars: fishing rights and political conflicts concerning the production of marine dyes in Hellenistic Greece, and Purpurarii in the western Mediterranean.
Most of the forms are completely sedentary remaining attached to hard substrata by thread-like byssus
of the foot or by one of their shell valves.
Mussels secrete a glue-like sticky material, known as byssus
, which is responsible for the strong adhesion to rocks and other surfaces in turbulent marine environment .
Bivalves fixed by byssus
or those cemented by shells prefer such offshore biotope.
